COGEN Europe Changing the way Europe provides heat and electricity
for a sustainable future

The role of heat in the EU
economy

Europe is home of leading cogeneration
manufacturers
6
Cogeneration in the European Economy:
• Employs 100,000 citizens in the EU
• Approximately 30 billion Euro turnover
• Supplies around ~12% of electricity and ~15%
of heat

Active power gene-
ration management
Transition from fossil to renewable dominated
generation
Intermittent power
generation by rene-
wables
Reduced re-active
power compensation
by renewables
Higher sensitivity to
load changes due to
reduced inertia
Change of operating
regime of fossil
generation
Low utilization of
existing fossil assets
Increase operational
flexibility of supplier of
residual load
Upgrade of existing
still operating fossil
power plants and new
business models
Change of business

Where will our heat come from in the future?
Cogeneration
Facility
Its only lost if you cannot use it
STRONG FOCUS TODAY ON
ELECTRICITY PRODUCTION
Wind Turbines
Photo voltaic
Nuclear
BUT WHAT ABOUT HEAT?
WILL WE USE ELECTRICITY FOR ALL
HEAT IN THE FUTURE?
PROBABLY NOT WE WILL STILL
DEPEND ALSO ON BURNING FUELS
NEED FOR OPTIMISED HEAT AND
ELECTRIC ENERGY SOLUTIONS

Generator Set For Fenice, Scarlino, Italy
Combined Heat and Power - Chemical Industry
Project Summary
Project / Country Fenice Scarlino, Italy
Customer EDF Fenice (EndUser: Huntsman Tioxide Plant)
Application Combined Heat and Power
Technology 1 x SGT-400 gas turbine packaged by Centrax
Electricity generated: 12.9 MW
Start 2013
Complete 2015
Challenge
• Continues operation at Huntsman‘s pigment manufacturing
facility in Scarlino
Solution • Siemens SGT-400 gas turbine to provide up to 12,9 MW of
electricity plus 24 tonnes of supperheated steam from the
turbine exhaust through a Heat Recovery Steam Generator for
the manufacturing process
• Most of the electricity generatied by CHP is consumed by the
Huntsman‘s Scarlino facility with any additional power being
exported to the local electricity grid
• Turbine intake air cooler to increase power output and efficency
in hot weather
Benefits
• Security of electrical supply to the Scarlino facility
• High efficiency reducing plant energy costs
• Reduced global green house gas emissions

Tri-Generation plant Fuel Flexibility with Low
Emissions in CoGen Riverbay, New York
Project Summary
Project / Country Bronx, New York, USA
Customer Riverbay Coorporation
Application Combined Cycle Cogeneration
Technology 2 x SGT-400 gas turbine, 1 x SST-300 with, Heat Recovery Steam
Generator (HRSG) and SPPA-3000
Start 2007
Complete 2008
Challenge
• Very short installation and commissioning time
• Reliable power supply for Co-op city for 60,000 residents for
heating, cooling and electricity
Solution • Tri-generation of heat and cooling 13.6 to 226 tonnes/hr steam
at 11bar, 9t/h chilled water and power 40 MW(e) (14 – 23 MW
own use in Co-op City, up to 16 MW export to local grid)
• Dual fuel burning capability of SGT-400
Benefits
• Customers savings ~$16 million Payback time 3 – 4 years
• High overall efficiency of >77 %
• Low emissions NOx < 10 Vppmd
• Tri-generation (heating, cooling and electrical power)
“Hurricane Sandy hit Co-op City about as hard as it hit
most anywhere else in New York City, but everybody in
Co-op City had power before, during and after the
storm.” said Freedman

Concluding remarks
cogeneurope.eu
Some recommendations for the Heating
and Cooling strategy
14
The Strategy should take a System not a Silo
approach
Success must be measured against primary energy
metric
Decarbonisation of energy in industry shall get a
special attention
Cogeneration principle should be highlighted
